As a side note, most of the time, all you need is 8-bit editing.
Quoted from
Adam Alexander on G+:
"By default, its "RGB Color" colorspace handles the same range of colors as the "millions of colors" that you see every other program use... That is 8 bits per color, plus an optional additional 8 bits for an alpha channel (transparency). This is 24 or 32 bit color, depending on how you handle the alpha channel.
That's vastly different from 8 bit color, which leaves 2 bits per color if you have alpha, or it allows for a pallet of 256 different colors... 2 bits per color wasn't even useful in the CGA graphics days, which is why GIFs use pallets.
Unless you have a monitor with a contrast ratio higher than 1:10,000, you will not be able to see any difference between 32 bit color and 64 bit color. If you're actually in advertising, you should know that your ad will not be seen on a top-of-the-line monitor. If it gets printed out in a magazine, then 6 bits per color is more than enough, if it's printed on a banner, then you might as well save the file in GIF format and be happy with your 256 color pallet. If the media is going to stay digital, then you'll never have it seen in good enough condition to see the very very subtle differences between 32 and 64 bit color anyways... If it's being projected (such as at a rock concert, or as an ad before a movie), there's no chance of the color depth being preserved due to the screen itself. Even if it's projected onto an IMAX screen, you'll never get the 1:10,000 contrast ratio you need in order for it to make a difference.
Even if the media stays on computer screens, the media does no good if it stays on your own computer... Sure your client might have a good screen... but who else does? Gamers do. That's it. Advertisers and gamers have good monitors, and the rest of us are more than happy to not give a ****. You know who among gamers or advertisers are actually going to see your ad? None of them. Both groups are computer savvy enough to be banner blind, and gamers all install Adblock.
So, it's nice for advertisers to pat themselves on the back... but is $700+ really a good investment for something that you, and only you, will ever see, much less actually notice?"
